Title: Ignition controller for internal combustion engine
Inventor: TAICHI YOUSUKE
IPC: F02D41/22
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To cut ignition for an internal combustion engine effectively while eliminating the influence on the other control. SOLUTION: An ignition signal generation means 10 generates ignition signals to cause a spark plug 2 to discharge in synchronism with the revolution of an engine 1. An engine speed calculation means 11 calculates the speed of the engine 1 per unit time based on the period of the ignition signals. If the engine speed exceeds a predetermined speed, an ignition cut means 12 checks the feed of the ignition signals. During the ignition cut, since the calculation means 11 can not obtain an accurate engine speed, an engine speed correction means 13 stores typically the mid value between the reference value for ignition cut and the engine speed estimated for the period after the completion of ignition cut into a RAM 15 as the standard value, and feed a correction value for engine speed to an ECU used for the other control.

IPC: H01L29/872
Filed: 1983-03-17
Abstract: PURPOSE:To improve the contact of an electrode with a lead and reduce the contact resistance by a method wherein a metal plated layer caused by field plating using a Schottky electrode as one electrode is interposed between the Schottky electrode and a base metallic layer to form a beam lead. CONSTITUTION:Two mesa grooves are bored in the surface of a semiconductor substrate 1 by etching, where an ohmic electrode 8 is buried, and then the Schottky electrode 9 is formed on the surface of the substrate 1 positioned therebetween. Next, the entire surface including those is coated with polyimide resin 10. Using hydrazine hydrate series etchant, an open hole 14 positioned on the electrode 9 is bored, and then the thick Au plated layer 15 is formed by field plating. Thereafter, an open hole 16 is opened in the resin 10 by being positioned on one electrode 8, and the base metallic layer 12 is adhered over the entire surface including said hole and thus made to abut against the electrode 8 and the layer 15.

Title: Vehicular power transmission device
Inventor: IWAO NOBUYUKI
IPC: F16D48/02
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To raise the temperature of clutch control oil in a short time and shorten a warming-up time by installing a control means for operating an actuator to shift a transmission in a neutral range, when oil temperature is equal to or lower than the preset value, and controlling hydraulic pressure for connecting a friction clutch. SOLUTION: Oil temperature Toil detected via an oil temperature sensor 8 is preliminarily stores for comparison with a certain threshold value Ts at a step 1. When Toil is equal to or lower than Ts , a process proceeds to the next step and an actuator 84 is operated to shift a transmission in a neutral range at a step 2. Hypoid gear oil generates high agitation resistance within the transmission at low temperature. On the other hand, a pump is rotated by an engine at a relatively high speed at a warming-up process. As a result, a remarkable differential rotation occurs across the pump and a turbine within a torque converter, thereby suddenly agitating oil in the torque converter and raising the temperature thereof in a short time to such an extent as allowing an engine start. At the same time, a warming-up time is reduced.

Filed: 1984-03-12
Abstract: PURPOSE:To omit the control of a stopper which controls the initial position of a carriage and to simplify the device constitution, by always setting the initial position of the carriage which is driven by a stepper motor at a place outside the detection area of a position detector. CONSTITUTION:A ROM2 storing the control programs including a carriage control program and a stepper motor 3 which drives a carriage of a magnetic head are connected to a CPU1 which controls totally a magnetic disk device. Furthermore a sensor 4 which detects the position of the magnetic head is connected to the CPU1. Then the CPU1 controls the drive of the motor 3 by the detection output of the sensor 4 and according to the control program stored in the ROM 2. The magnetic head is shifted to a non-detection area and then to a detection area in case the initial position of the magnetic head is set within the detection area of the sensor 4 in a control action mode. Then the 0-phase energization is performed when the head enters its detection area. Thus it is possible to omit the control of a stopper which controls the initial position of the carriage.
